1 Claim. (Cl. 189--72) The characteristic of the present invention is the provision for sliding window sash for sliding windows, including windows used in automobile bodies, and for other Y closures, of compensating weather and anti-rattle bearings which consist in the combination of bearing rails or tracks and specially formed resilient carriers therefor, so designed that prior to the insertion of the windows or other movable closures the spacing between opposite bearing rails or strips for a given window is less than the width of the window or closure to be received therebetween. This compels an outward lateral movement of the bearing rails or strips, and a continuous reaction of the elastic carrier in such manner that notwithstanding wear on the bearing rails or strips the latter are maintained in sealing and anti-rattle operation upon the said closure, the latter generally being a sliding closure.

These and other objects of the invention will be described from a reading of the following specification thereof, in conjunction with the accompanying drawings, in which:

Fig. l is a vertical section through the lower portion of a window sash and sill frame member, the latter carrying an embodiment of the invention; the dotted lines indicating the initial spacing of the bearing rails or strips relatively to the sash;

Fig. 2 is a view similar to Fig. 1, the sash being shown in operative position;

Fig. 3 is a sectional view of a modied form the bearing disposed in the cavity of a sill member;

Fig. 4 is a view similar to Fig. 1 illustrating a further modification of the invention, the slide rails or strips having tongues which enter side grooves in the sash frame.

Referring to the drawings, and particularly to Fig. l, there is shown a Window bearing assembly mounted in a box-like sill member 1, and consisting of a U-shaped compensating support 2 having good elasticity, and which may be of rubber or other material, natural or synthetic, having the desired elastic properties. It has a at base wall and side walls perpendicular thereto.

The bearing rails or strips 3 are angular, and one of these ts over each of the inner top margins of the compensating support 2. The bearing rails or strips 3 may be of rolled or extruded metal, plastic or other desirable bearing material. If desired, these strips may be secured to the compensating support by any suitable means. For purposes of illustration, a layer of bonding material is shown at 4.

The compensating support 1 may be seated in any suitable window or door frame, depending upon the United States Patent O 2,796,960 Patented June 25, 1957 use to which it is to be put. In Fig. l the compensating support is positioned in the sill 1 of a window frame, and the channel shape thereof provides support for the base wall and side walls of the compensating support. The inner ends of the sill side walls are preferably provided with flanges 1x which overhang the elastic compensating support.

A window sash member 5, carrying a window pane 6, is shown in Fig. l, being shown in position for insertion between the bearing rails or strips 3. The distance d between the opposed faces of the bearing strips is slightly less than the distance dz, which latter is the dimension of the sash cross-section. Consequently, when the sash is inserted the elastic walls of the compensating support member 2 must yield, and the reaction force thereof provides continuing tight contact between the bearing rails 3 and the outer sash surfaces.

Fig. 2 shows the sash 5 fully inserted in the window frame sill 1. As may be seen, the bearing rails 3 provide a tight seal for the sash. At the same time, due to the yield factor of member 2, the sash is readily slidable.

In Fig. 3 a single U-shaped bearing rail 7 is employed. Rail 7 lits snugly within compensating support 2., lining completely the inner wall surfaces thereof, and it has flanges 7x at its outer ends which abut the upper exposed surface of the compensating support.

Fig. 4 discloses a further modification, in which the bearing rails 3x, of the general type shown in Fig. 1, are provided with inwardly extending tongues 8. Grooves 9 are provided in the opposite walls of the sash 5x, said grooves conforming with the tongues. An additional sealing effect, as well as a latching-guide action, is then obtained when the sash is inserted in the bearing member.

Although the present invention has been described with reference to an embodiment thereof in the form of slideways for window sash, it is adapted for use with doors and all types of movable closures.

vWhat is claimed is:

In a closure of the type comprising a bearing and a slidable closure member therein, such as a window, a compensating seal and anti-rattle bearing comprising an elastic longitudinally channeled compensating support having bearing rail means carried thereby, said bearing rail means abutting the inner corners of the channel side walls of said compensating support and providing yielding-backed bearing surfaces, and in combination therewith a closure member entering said channel of the compensating support, said closure member having at least one guide groove, at least one of the bearing rails being formed with a longitudinally extending tongue entering a groove of the closure member, and said closure member being slidable within said channel and along said tongue.
